Hi,
I use a function: TGraphErrors::ComputeRange(Double_t &xmin, Double_t
&ymin, Double_t &xmax, Double_t &ymax) to calculate limits of my
graph. I see the strange behaviour of this function - the result
depends on the initial value of &xmin, &ymin etc.
For example, if I have the real range of a plotted function from 200
to 300 it calculates maximum ymax=300 (it's ok) and ymin=0 (wrong). If
I set ymin=1000 before, it computes ymin=200 (ok).
The same error is for all parameters.
Thus, this function use the initial value of parameter and, if the
parameter out of range of the graph, for instance, if the initial
value ymin is less than actual y-minimum of the graph, then
ComputeRange keeps it as the minimum.
It's really mistake or might be I do something wrong with the function?
ROOT: 5.17.02 for Windows, recommended version.
